Comprehensive study of serine/arginine-rich (SR) gene family in rice: characterization, evolution and expression analysis.

ABSTRACT: As important regulators of alternative splicing (AS) events, serine/arginine (SR)-rich proteins play indispensable roles in the growth and development of organisms. Until now, the study of SR genes has been lacking in plants. In the current study, we performed genome-wide analysis on the SR gene family in rice. A total of 24 OsSR genes were phylogenetically classified into seven groups, corresponding to seven subfamilies. The OsSR genes' structures, distribution of conserved domains, and protein tertiary structure of OsSR were conserved within each subfamily. The synteny analysis revealed that segmental duplication events were critical for the expansion of OsSR gene family. Moreover, interspecific synteny revealed the distribution of orthologous SR gene pairs between r
